Description
The SMP1321 series of plastic packaged, surface mountable PIN
diodes is designed for use in high volume switch applications
from 10 MHz to more than 10
GHz.
The low capacitance of these
diodes (0.25 pF), combined with a low resistance (2.0
Ω
maximum at 10 mA), makes the SMP1321 series particularly
suited to high isolation, series-connected PIN diode switches in
battery operated circuits.
The SMP1321 series is available in a selection of plastic
packages and a variety of configurations that include an SC-70, a
small footprint SC-79, a low inductance SOT-23, and a miniature
SOD-882.
Table 1 describes the various packages and marking of the
SMP1321 series.

SMP1321-007
For the -007 configuration of the SOT-23 package, the package
inductance is effectively reduced to 0.4 nH compared to the
1.5 nH value of the standard configuration. This lower inductance
is particularly beneficial when the diodes are used as shunt
connected switches at frequencies higher than 500 MHz in which
inductance is the primary limitation on maximum switch isolation.
To achieve the effective 0.4 nH, the SOT-23 package must be
inserted in the microstrip circuit board with a gap in the trace, as
shown in Figure 1. Because of the polarity of the diode junction,
this low inductance feature is realizable only with the cathode
connected to ground.
Gap
SMP1321 series are provided in Table 2. Electrical specifications
are provided in Table 3. Resistance versus temperature
measurements are provided in Table 4.
Typical performance characteristics of the SMP1321 series are
illustrated in Figures 2 to 5. Package dimensions are shown in
Figures 6 to 14 (even numbers), and tape and reel dimensions are
provided in Figures 7 to 15 (odd numbers).
Package and Handling Information
Instructions on the shipping container label regarding exposure to
moisture after the container seal is broken must be followed.
Otherwise, problems related to moisture absorption may occur
when the part is subjected to high temperature during solder
assembly.
The SMP1321 series is rated to Moisture Sensitivity Level 1
(MSL1) at 260
C.
It can be used for lead or lead-free soldering.
For additional information, refer to the Skyworks Application Note,
Solder Reflow Information,
document number 200164.
Care must be taken when attaching this product, whether it is
done manually or in a production solder reflow environment.
Production quantities of this product are shipped in a standard
tape and reel format.

Note 1:
Exposure to maximum rating conditions for extended periods may reduce device reliability. There is no damage to device with only one parameter set at the limit and all other
parameters set at or below their nominal value. Exceeding any of the limits listed here may result in permanent damage to the device.
CAUTION:
Although this device is designed to be as robust as possible, electrostatic discharge (ESD) can damage this device. This device
must be protected at all times from ESD. Static charges may easily produce potentials of several kilovolts on the human body
or equipment, which can discharge without detection. Industry-standard ESD precautions should be used at all times. The
SMP1321 series PIN diodes are Class 1A ESD devices.
